Locked Out While Upgrading SSL (Netbsd)

I was attempting to upgrade SSL on my netbsd machine and after a 'make install' I was logged out(I was logged in via ssh), and when I attempted to log back in(via ssh) I was given this message: "ssh_exchange_identification: Connection closed by remote host" So I went and attempted to log in the the actual machine and couldn't everytime I would enter any username including root at the prompt and hit enter I was not prompted for a password, it just asked for the login name again. I rebooted and the same thing happens. When I attempt to log in via ssh I get: "Connection closed by $IP". Any help is appreciated.

#NOTE I've already booted into singe user mode and looked for anything odd, but could find nothing(maybe I don't know what to look for). I also edited /etc/rc.conf to prevent sshd from starting to see if it was causing the problem, but it wasn't. And I reset the root password too just in case, but it had no effect. I'm out of ideas.

#FIXED Okay it seems I somehow screwed up the login script and it was crashing when I attempted to login. I just got out the old install CD, did an upgrade, and it's fixed.

SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8) NAME
ssh-keysign -- ssh helper program for host-based authentication SYNOPSIS
ssh-keysign DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with SSH protocol version 2. ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign to ``yes''. ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen- tication. FILES
/etc/ssh/ssh_config Controls whether ssh-keysign is enabled. /etc/ssh/ssh_host_dsa_key /etc/ssh/ssh_host_ecdsa_key /etc/ssh/ssh_host_ed25519_key /etc/ssh/ssh_host_rsa_key These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read- able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host- based authentication is used. /etc/ssh/ssh_host_dsa_key-cert.pub /etc/ssh/ssh_host_ecdsa_key-cert.pub /etc/ssh/ssh_host_ed25519_key-cert.pub /etc/ssh/ssh_host_rsa_key-cert.pub If these files exist they are assumed to contain public certificate information corresponding with the private keys above. SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8) HISTORY
ssh-keysign first appeared in OpenBSD 3.2. AUTHORS
